The http-equiv attribute provides an HTTP header for the information/value of the content attribute.
The http-equiv attribute can be used to simulate an HTTP response header.
content-type Specifies the character encoding for the document.
Example:
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
default-style Specified the preferred style sheet to use.
Example:
<meta http-equiv="default-style" content="the document's preferred stylesheet">
Note: The value of the content attribute above must match the value of the title attribute on a link element in the same document, or it must match the value of the title attribute on a style element in the same document.
refresh Defines a time interval for the document to refresh itself.
Example:
<meta http-equiv="refresh" content="300">
Note: The value "refresh" should be used carefully, as it takes the control of a page away from the user. Using "refresh" will cause a failure in W3C's Web Content Accessibility Guidelines.
